CARPETDSWEEPER.

SPECIFICATION forming part of Letters Patent No. 476,213, dated May 31, 1892.

Application filed July 22, 1891. Serial No. 400,369- (No model.)

T @ZZ whom it may concern: posite ends of a rod XV, which rod is inserted 5o Be it known that I, SLAs H. RAYMOND, a in slots O in the end walls of the sweepercitizen of thc United States, residing at Grand case, said slots having their upper ends in- Rapids, in the county of Kent and State of clined toward the brush-shaft.

Michigan, have invented certain new and use- At the middle of the side of the case oppoful Improvements in Carpet-Sweepers; and I site the driving-wheels is a bracket E, having do hereby declare the following` to be a full, a caster-wheel F attached, the pintle G of clear, and exact description of the invention, said caster being free to move vertically in such as will enable others skilled in the art to the bracket and provided with a verticallyro which it appertains to make and use the same. elastic spring H, surrounding said pintle, en-

My invention relates to improvements in gaging the yoke of the caster at its lower end 6o carpet-sweepers; and its Objectis to simplify and the bottom of the pintle-socket at its and reduce the cost of construction and to upper end. Said brush-shaft is journaled in provide the same with certain new and use hangers J, which are flexible in adirection at i 5 ful features hereinafter more fully described, right angles to the axis of the brush-shaft,

The tension of A is the case, and B the bail-socket, prothis spring lifts the pin and through the rods 3o vided with a ring B at its lower end, having T closes the pans, and when the push-pin I a large opening, which is filled with rubber is depressed the pans are opened to discharge 8o or other elastic material P, in the center of their contents. As pressure is applied to the which is a metal bushing Q, through which handle the rod W moves along the slot O dipasses the pivot-bolt D, which bolt also passes agonally upward and inward, and the brush- 35 through the angle-plates O C, which plates shaft moves laterally into the extensions U are secured to the case at each side of the as the hanger is laterally deflected. At the ringB. On each side of the bail-socket Bare saine time the casterhanger compresses the convex projections B, which engage corre spring H, thus lowering the case toward the spending concave seats O in the upper part floor at both sides and bringing the brush in 4o ofthe plateOwhen the bail-socketis vertical. close contact with the carpet. The caster K is a band of rubber encircling the case wheel being located so far away from the 9o and serving to prevent scratching or marring wheels M gives a broad base and reduces the of furniture struck by the sweeper. tendency to tilt the case. The elastic bush- L is the brush-shaft, having driving-pulleys ing P forces the projections B into concave 45 L at each end. Said shaft is inserted in seats O', and thus sustains the handle in a openings U in the ends of the case, said openvertical position, and when the handle is inings having 'lateral extensions U on the side clined the friction of bail-socket B .against opposite the driving-wheels, of which there the sides of angle-plates O serves to steady are but two, which are journaled on the opthe handle, and by mounting the device on three wheels-one of which is a caster- Wheel-it turns about in curved lines of motion very easily.

What I claim s-d l. In a carpet-sweeper, a brush-shaft journaled in laterally-flexible hangers and driving-wheels at one side of said brush-shaft journaled on a rod passing through inclined openings in the case, in combination with a caster-wheel-on the side of the case opposite said driving-wheels and a spring engaging said caster-wheel and adapted to be depressed on the downward movement of the case when the latter is being lowered, as described.

- 2. In a carpet-sweeper,ahandle-socket having a ring at its lower end surrounding an elastic bushing, through which passes a pivotbolt, angle-plates at each side of said ring secured to the case, having depressions at their upper sides, and projections on the sides of said socket engaging said depressions, substantially as described.

3. In a carpet-sweeper, a push-pin having a T-head, connecting-rods pivoted to the same and to the dust-pans near the pivots of said pans, and a lifting-spring engaging the end of said push-pin, substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
